DESCRIPTION

The BUL310 and BUL310PI are manufactured

using

high

voltage

Multi

Epitaxial

Planar

technology for high switching speeds and high

voltage capability. They use a Cellular Emitter

structure with planar edge termination to enhance

switching speeds while maintaining a

wide

RBSOA.

The BUL series is designed for use in lighting

applications and low cost switch-mode power

supplies.
